英文:
How do I add a delay to a script tag that includes params?
问题
我想为这段代码添加延迟，包括async和data属性。
<script async src="https://s.widgetwhats.com/wwwa.js" data-wwwa="1"></script>
我在stackoverflow上看到了这个解决方案链接在此，但它不包括参数。
英文:
I would like to add a delay for this code including the async and the data attributes.
<script async src="https://s.widgetwhats.com/wwwa.js" data-wwwa="1"></script>
I saw this solution on stackoverflow enter link description here but it doesn't include the parameters.

async属性的<script>表示它将在下载后立即执行，不管页面的其余部分是否已加载。
如果您想在加载<script>之前有延迟，可以删除async属性，并使用setTimeout函数来延迟执行，如以下方式：
<script>
setTimeout(function() {
var script = document.createElement('script');
script.src = "https://s.widgetwhats.com/wwwa.js";
script.setAttribute('data-wwwa', '1');
document.body.appendChild(script);
}, 2000); //延迟时间以毫秒为单位（2秒）
</script>
英文:
script with async attribute means it will be executed as soon as it is downloaded, regardless of whether the rest of the page is loaded.
If you want a delay before loading the script, you can remove the async attribute and use the setTimeout function to delay the execution like the following way:
<script>
setTimeout(function() {
var script = document.createElement('script');
script.src = "https://s.widgetwhats.com/wwwa.js";
script.setAttribute('data-wwwa', '1');
document.body.appendChild(script);
}, 2000); //delay in milliseconds (2 seconds)
</script>
